Here is a running list of thread sizes that I've kept in my notes.  If anyone can add to these, it would be great.  Actually, it would be nice if we could assemble a list of all the thread sizes for bolts in the engine too.  I just wish I had kept better notes on some of these things.

Water temp in water pump housing- M12 X 1.5

Oil temp (in pan)- M16 X 1.5

Oil pressure- M10 X 1.0

 

Other fittings-

The front cover oil outlet fitting is a 16mm X 1.5

the drain plug appears to be a 14mm x 1.5 (haven’t verified that yet). 

the port for oil return on the rear housing is an 18mm x 1.5.   

  

Can someone add to this list the bolt size for the larger bolts in the oil pan that were used for the auto engine mount?  I need to fill these holes, can't pour oil in fast enough to keep oil in engine.
